    Cryptographic Approach to Patient Records Privacy Protection in Emergency Situations
    (2004-06) Kapis, Kosmas; Van Der Lubbe, Jan C.; Cartrysse, Kathy
    This paper presents cryptographic mechanisms for securing electronic medical patient records, EPRs in emergency situations. The mechanism maintains the EPR confidentiality during an emergency when a patient is unconscious and located outside any health provider, HP. In such situations any authorized health care practitioner, HCP can access all relevant medical records when needed. However, after such an emergency, it is impossible for anyone to access the patient’s EPR without the patient’s consent. This can be achieved by using a modified forward-secure signature and encryption algorithm used in two directions. After an emergency treatment, the patient’s consent is restored.

    Security Mechanisms For Electronic Patient Records In Mobile Intelligent Services
    (MEDINF, 2003) Kapis, Kosmas; Van Der Lubbe, Jan C.
    The deficiencies found in conventional paper-based patient records, practiced in healthcare service provision, have resulted in the emerging development of electronic patient record (EPR) systems. This paper proposes a cryptographybased EPR security model guaranteeing the patient’s record integrity, accountability, confidentiality and patient record access consent. For this model several possible cryptographic security mechanisms are studied. The advantages and disadvantages of each scheme are considered, and based on the EPR requirements the mechanism with best results is suggested.

    Security Scheme for Electronic Patient’s Records Incorporating Full Privacy
    (2010) Kapis, Kosmas; Van Der Lubbe, Jan C.; Cartrysse, Kathy; Gedrojc, Bartek
    This paper presents an electronic patient record (EPR) security scheme that covers the privacy of patients and health care practitioners (HCPs). The scheme is designed such that it provides HCP’s privacy towards another HCP but revealable in disputes. Forward signature and encryption schemes are used to provide EPR integrity and confidentiality respectively. Furthermore, forward group signatures are used to provide privacy between HCPs.
